How to check if the string begins with specific substring in Java?
A String class can be used to represent the character strings, all the string literals in a Java program are implemented as an instance of a String class. The Strings are constants and their values cannot be changed (immutable) once created.
We can use the startsWith() method of String class to check whether a string begins with a specific string or not, it returns a boolean, true or false.
Syntax
public boolean startsWith(String prefix)
Example
public class StringStartsWithSubStringTest {
public static void main(String[] args) {
String str = "WelcomeToTutorialsPoint";
if(str.startsWith("Welcome")) {
System.out.println("Begins with the specified word!");
}
else {
System.out.println("Does not begin with the specified word!");
}
}
}
Output
Begins with the specified word!
